NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Apr. 11, 1911.

" Application filed January 27, 1910. Serial No. 540,433.

To all whom it may concern.'

Be it known that we, EDMUND S. PARsLoW and EDWARD T. HIGGINS, both citizens of the United States, and resident-s of New York, county and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a full, clear, and exa-ct specification.

Our invention relates to non-refillable bottles and comprises means for preventing the reillin of the bottle after the original contents therein have partly or entirely been poured out or discharged.

' There are a great many so-called nonrefillable bottles on the market, but they are in the most instances impractical and rather adapted to defeat the object for which they were designed, or they are of too expensive construction to be of any useful value in commerce. It has been found that under a few atmospheres of pressure the aforesaid so-called non-refillable bottles can be refilled .as the valves of the same do not effectively remain practically tight under atmospheric pressure and therefore do not properly prevent the refilling operation. In other devices of this kind the valves can easily be kept open by the insertion of a wire, or the like, and consequently they are also of little or no value.

The object of our invention is primarily to overcome these objectionable features by providing a tubular protective cap adapted to be placed over and secured by suitable means to the shortened neck of a bottle so as to prevent removal of said cap in case of attempts being made to gain access to the interior of the bottle for the purpose o f'refilling'the same with fraudulent intention. With this end in view we employ various means for connecting said cap to the bottle, said means consisting mainly in providing the bottle with spring-snaps suitably arranged so as to firmly grip the shoulders or engage the notches of said cap, or the bottle may be provided with 4threaded shoulders adapted to engage the threaded interior of the bottom of said cap; or the shoulders of said bottle may be vertically slotted and provided with a communicating annular groove for receiving the teats provided on the interior of said cap for holdin the same by frictional contact to the shoul ers of the bottle.

. We further provide for destroying or damaging the bo-ttle so as to prevent rellin g in case of attempts being made to remove the cap therefrom, and this object is attained by providing deep recesses at the point of connection of the neck with the body of the bottle so that by the administration of force the neck will break oit thereby making it impossible to re-use the bottle.

Furthermore, our cap consists in providing an eificiently arranged valve adapted to permit the contents of the bottle to be easily and readily poured therefrom, but the novel form of said valve and advantageous constructive parts of the cap in operative relation thereto are such that said valve will always remain seated, and the bottle thereby closed against introduction of liquid under atmospheric pressure as the force of the liquid upon said valve will be above the center of gravity no matter in what position the bottle may be placed, and the bottle will also be closed should a wire or other means be used to unseat said valve for the purpose of allowing the bottle to be re-fllled.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification ,in which similar characters of reference indicate corresponding part-s in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a vertical longitudinal section through the neck of a bottle and the protective cap and the parts contained therein of one form of our invention. Fig. 2 is a section therethrough along t-he line II-II of Fig. 1. Fig. 3 is a similar section along the line III-III of Fig. 1 seen from above. Fig. 4 shows a modified form of the means for securing the cap to a bottles neck. Fig. 5 shows another modified form thereof, and Fig. 6 is a detail fragmentary sectional view showing still another modified form of connection between the cap and bottle neck.

Upon the neck 10 of a bottle 11 of any y desired shape, form or material is secured a cap 12 preferably of glass, porcelain or any other suitable material which will answer the purpose for which it is devised. The protective cap 12 is provided in its wall with a plurality of vertically arranged grooves or channels, as at 1B, for passage therethrough of liquid, and said grooves communicate at the bottom thereof with an annular' groove 14 intermediate the len th of the cap and form downwardly extending notches 15.

To permit liquid to be readily poured from within the bottle, but to positively prevent the bottle from being refilled and 1 also preventing foreign substances from being forced into the bottle to contaminate the contents therein, we provide a valve 16, comprising a body part 17, the upper portion of which having shoulders 18, 18 formed by the base of the projecting part 19, being somewhat smaller in circumference than the body part 17. The projecting part 1 9 may be of any desired shape, but vas ind1- cated at 20, is preferably conical in form, and to guide the valve 16 back to its seat after displacement said cone is adapted to enter recess 21 formed in the diaphragm 0r solid ieces 22 within the neck of the cap 12. hus it is obvious that sho-uld at tempts be made to relill the bottle with liq- For the purpose of providing a suitable seat :tor the valve 16, a substantially cupshaped disk, as at 23, may be arranged withl This disk 23 is centrallyf I hooks may be formed by slotting the `free in the cap 12. apertured at 24, for mainly as an outlet for the liquid in the bottle, but also insuring, as

will be seen, perfect closing of said aperture by the semi-.circular underside 25 of,

wardly and outwardly from the neck 10,

the valve 16 conforming with the conguration of the inner surface of the cup 26 of the disk 23. The lip 27 of the cup-shaped would be deflected by sliding along the shoulder 18 Aand the mantle of the cone 19 of the valve 16,and thereby any attempt to open the valve and refill the bottle will be successfully proportions of the parts forming our .im-

foiled.

To prevent the removal of the protective cap from the neck of the bottle spring hooks or catches 27 a are provided in any convenient may be screwed upon the neck 10 of the bottle 11 by an inner thread as at 32 en aging the threaded head 33 of the neck o the bottle, and said neck at the point of connection with the body of the bottle 11 is provided with deep recesses 34, 34 serving to weaken the bottleneck to such an extent that it will easily break oft' at this point and damage the bottle so that its .reuse will be impossible should force be used toy remo-ve the cap from the neck for the purpose of gainin access to the bottle with the intention o refilling the same.

In Fig. 5 another modified form for connecting the protect-ive cap 12 to the bottle 11 is .shown wherein the vertical grooves 35 and the annular grooves 36 are provided inthe neck of .said bottle and adapted` to receive the teats 37 of the protective cap 12. In this form the cap 12 is placed over t-he neck of the bottle 11, the teats 37 first entering the vertical grooves 35. The cap 12 being turned after being pressed downward, the teats 37 then entering the annular grooves 3G,

and thereby said cap is firmly held by fric-V bottle 11 consisting in provi ing downwardly projecting spring-hooks .31 the upper ends of which being embedded `in the top of the neck 10. Any number of the springhooks or catches 31 may be used, or said end of an annular band held to the bottle neck in any suitable manner The free ends 3.1a of said hooks or catches extend downsaid ends engaging the shoulders or notches 31b formed bythe inwardly projecting annular flange 31c of the enlarged part 31d provided at the base of the protective cap 12. In connecting the cap 12 with the bottle 11 the former is placed over the bottleneck 10, the annular flange 31 in its downward direction pressing inwardly the spring-hooks 3l which are released and grips the notches 3.1b when the bottom of theca 12 reaches a point .adjacent to the top of the ottle prnper; thus providing ,a very .simple and eclent means for securely holding Ythe protective cap l2 to the neck of the bottle.

Changes may be made in the shape and proved non-.relillable bottle without departing from the scope of the present invention as described, illustrated and laid down in the claims, therefore, we donot wish to' be limited to the articular form .of valve and arrangement o other parts as herein .described, shown and claimed .Having thus described our invention, we claim as new and desire to secure `by Letters Patent: s
